The Lowdown
Gather 'round, folks. Rusty here. Let's be real straight up: the next two weeks at Kennebunk Beach are looking pretty grim. The forecast is calling for "poor surf conditions" across the entire 16-day window. That's a long stretch of nothing special. We've got a few tiny pulses of energy, but nothing that's gonna get your heart racing. The good news is that if you're desperate, there are a few moments where the wind might line up, but you're gonna have to be patient.
The first sign of anything surfable is on Friday, August 21st. It's small, really small. We're looking at a 2ft swell from the ESE at 8 seconds. That's short period, weak energy (58). The wind is a gentle offshore breeze from the ENE, so the surface will be clean, but there's just not enough push to make it worthwhile. It's a "poor surf conditions" call, and I'm with it.
Saturday, August 22nd, is even smaller. The morning shows a 1ft ESE swell at 8 seconds (38 energy). The wind is offshore from the ENE, so it's clean, but it's tiny. The afternoon brings a bit of rain but the same clean, small, poor conditions.
Sunday, August 23rd, is the best of a bad lot, and it's still not great. The morning has a 3ft ESE swell at a short 6 seconds (59 energy). The wind is a light cross-offshore from the NNE, so it's clean. The afternoon gets glassy with a 2ft swell from the ESE at 6 seconds (51 energy) and a glassy wind from the S. This is the only window that might be worth a paddle on a longboard, but it's still a poor surf day.
Monday, August 24th, sees a tiny bump in energy with a 3ft SE swell at 6 seconds, but it's onshore wind from the SSW and SW. The energy is moderate (132 and 115), but the wind is terrible, making it a poor option.
From Tuesday, August 25th, through to the end of the month, it's a long stretch of tiny, weak swells and mostly cross or onshore winds. The only real standout is Thursday, August 27th, where the wind is light and cross-shore, but the swell is only 2ft at 7 seconds (48 energy). It's just not enough.
Now, we get to the end of the period on Monday, August 31st, and the swell finally tries to show up. The morning sees a 4ft swell from the SSE at a terrible 5 seconds (99 energy), but it's onshore. The afternoon gets a 7ft swell from the SSE at 6 seconds with a whopping 318 energy! That's a strong, powerful swell. But the wind is cross-onshore from the SSE, which will make it choppy and messy. This is a big, powerful, ugly wave. It's going to be a washing machine. For the experts only, and even then, it's a maybe. This is more of a kite-surfing day than a paddle-surfing day.
The first week of September is more of the same: small, weak, and onshore. The water temperature is about average for this time of year, so no surprises there.
In short, Kennebunk Beach is in a flat spell. There is no good surf in the 16-day window. The only real standout is the pulse on August 31st, but it's a messy, powerful, onshore wind swell that's only for the brave. If you're looking for clean waves, you're going to be waiting a while. Forecasts can change, but right now, it's a tough call.

Information about the Kennebunk Beach Surf forecast
The above surf forecast table for Kennebunk Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kennebunk Beach can be found by selecting the local surf guide option on the grey menu. Our Kennebunk Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Kennebunk Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Kennebunk Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
